Letters Patent No. 93,195, (lated August 3, 1869.

IMPROVEMENT IN LIFE-PRESERVING- MATTRESS.

The Schedule referred to in these Letters Patent and making part o f thefsame.

To all whom 'it may concern:

Be it known that LDAVID E. HALL, of Detroit, in the county of Wayne, and State of Michigan, have invented ceitaili' new and useful Improvements in a Bed and Life-Preserver combined; and I do hereby declare that the following is a full and complete description of the same, reference 'being had -to the accompanying drawings, making part of this specification, in which- Figure 1' is a perspective view of the bed and preserver.

Figure 2 is a vertical longitudinal section.

Figure 3, a transverse vertical section.

Like. letters of reference refer to like parts in the different views.

The nature ofthis invention, relates to a bed-bottom, so constructed, and in combination with certain other devices, that it becomes thereby a life-preserver and bed combined.

Fig. 1 represents a perspective view of the bed, which consists of the slats A, fig. 2, arranged lengthwise, a transverse View of which is shown in iig. 3.

Said slats rest upon an arrangementof short slats, B, interposed between the ends and the openings C, whereby they aresupported.

These short slats B are secured toeach Vother by means of a covering, D, the slats and springs being separate structures, and independent ofthe longitudinal slats, being a kind of pillow or support for the springs and slats.

E, iig. 2, are sacks-filled with -eork chips, or other light., buoyant material. v

Said sacks or iioats are interposed between the ends of the slats A, and on the outer side of the springs and slats B, thereby forming the extreme ends or walls of 'the bed-bottom.

By this arrangement of floats, slats, and springs, it will be obvious that a substantial, elastic, and durable bed-bottom is obtained, and, at the same time, an avail,-

able means for the preservation of life, in case of accident, when the bed-bottomA is used on board o f steamboats and other vessels.

As the whole arrangement is enclosed in a strong coveringor case, F, as shown in fig.'1, it is thereby 'I made one entire thing, so that it can be handled with as much ease and facility as a common mattress; hence it can be put upon' or taken oif from the bedstead or bunk at a moments notice, and used as a oat or raft, for the preservation of life.

By means ot' the loops G, whereby it is handled, a number of them can be strapped together, and thus form a large'and oommodious raft, for the accommodation of a number of persons.

vWhat I claimA as my improvement, and desire to secure by Letters Patent, is

` The slats A B, spiingsO, and iloats E, when combined and arranged, in relation to each other, substantially as and for the purpose set forth.

DAVID E. HALL.
